> In HIVE-5263 we started serializing OI's when cloning the plan. This was a great boost in speed for many queries. In the future we'd like to stop copying the OI's, perhaps in HIVE-4396.
> Until then Custom Serdes will not work on trunk. This is a fix to allow custom serdes such as the Hive JSon Serde work until we address the fact we don't want to have to copy the OI's.
